A few weeks ago my brother and I took a trip to Rotterdam. I’d never been in the city proper before, only to concert venues on the fringes, and I was surprised at how modernist and industrial it is. To get the Netherlands to surrender, the Germans bombed Rotterdam on May 14 1940, threatening to do the same to other cities, like Utrecht. Rotterdam used to resemble Amsterdam in its architecture, but is now full of interesting postwar and more recent buildings. For architecture and culture, Rotterdam is hard to beat.
